Markaudio Alpair-11MS Grey Full-range Woofer

The Markaudio Alpair-11MS Grey 6.5" Full Range Woofer is a remarkable broadband driver that brings exceptional clarity and precision to compact audio systems. Designed for audiophiles who demand high-fidelity sound without sacrificing space, this driver excels in both stereo and home theatre setups, as well as in bespoke speaker builds where a single driver solution is preferred. Its full-range capability eliminates the need for a separate tweeter, simplifying crossover design while delivering a cohesive, natural soundstage.

Technically, the Alpair-11MS is engineered for controlled, articulate bass response, with a total Q factor (Qts) of 0.34 ensuring tight, well-damped low frequencies. The driver boasts an impedance of 8 ohms and a sensitivity of 88.1 dB (SPL 1m/2.83V), making it efficient and easy to drive with modest amplification. With a maximum linear excursion (Xmax) of 8 mm and a power handling capacity of 35 watts, it can produce dynamic peaks without distortion. The mechanical (Qms: 2.22) and electrical (Qes: 0.41) Q factors further refine its performance, while the 127 mm nominal diameter and 66 mm depth allow for versatile enclosure integration. The 171.5 mm overall diameter and 144 mm cut-out diameter, along with five mounting holes, simplify installation. With a DC resistance (Re) of 7.2 ohms, this driver from the Markaudio Alpair series is a superb choice for those seeking uncompromising sound quality in a compact form.
